Application process
1) Coating dry weight：Suggested coating dry weight between 3~4g/m2
2) Drying temperature：Suggested drying temperature 80-100℃，according to the drying situation；
3) Compound temperature：Suggested compound temperature 80-100℃
4)Curing condition：Suggested curing temperature 55-60℃，curing time 5-7days.
Test method
1) Peeling strength: 180°peeling, machine speed 300mm/min, record the average test value
2) Corrosion resistance: Add 0.1% water to LiPF6 electrolyte, then soak 15mm wide sample in it, place for a specified time to test the peel strength
3) Heat sealing performace：cut 15mm wide sample，seal with 190℃*1s*0.4MPa，to test the heat sealing strength, and observe the equivalence.
